The National Public Health Agency (NPHA), in collaboration with the Ministry of Health and Sanitation, conducted a high-level field supervisory visit to the ongoing Sierra Leone Population-Based HIV Impact Assessment (SILPHIA) survey on May 2, 2026. The delegation was led by Professor Dr. Foday Sahr, Executive Director of NPHA and Principal Investigator of the SILPHIA survey, accompanied by his Deputy, Alhaji Dr. Mohamed Alex Vandi, the Chief Medical Officer, Dr. Sartie Kenneh, and Dr. Eric Icona, Country Director of ICAP Sierra Leone. The NPHA Public Relations team also joined the visit, underscoring the importance of transparent communication and institutional visibility in national health initiatives. All members of the leadership present are seasoned medical doctors, bringing clinical expertise and scientific rigor to the oversight of this landmark survey.
The team convened briefly at the Waterloo Community Health Center, where they were welcomed by Mr. James, SILPHIA Coordinator. He provided a detailed account of the progress made so far, highlighting the dedication of survey teams and the positive community engagement that has facilitated smooth operations. He acknowledged that while there had been minor logistical challenges, these were swiftly overcome through adaptive planning and strong teamwork. He emphasized that the survey is currently being conducted in the Western Area only, with plans to expand coverage in subsequent phases.
Following the briefing, the delegation proceeded to the Waterloo community and later to the Tombo community, where SILPHIA field teams were actively working. The leadership observed sample collection processes firsthand, ensuring strict adherence to established protocols. Their presence reinforced the importance of maintaining high data quality standards and boosted the morale of the field teams. Speaking during the engagement, Dr. Sartie Kenneh commended the teams for their professionalism and dedication, stating, “Your commitment to accuracy and quality data collection is critical to shaping effective health interventions for our country.” Professor Dr. Sahr encouraged the teams to maintain the highest standards, noting, “We are proud of the work you are doing. Maintain these high standards, as the data you gather will guide national decisions and improve public health outcomes.” Dr. Eric Icona also made a brief statement, applauding the collaboration between NPHA, ICAP, and partners, and emphasizing that SILPHIA is not only about HIV data but also about strengthening Sierra Leone’s overall public health infrastructure, building capacity, and ensuring that communities benefit from evidence-driven interventions.
The SILPHIA survey is a landmark national exercise designed to measure the prevalence of HIV, assess treatment coverage, and evaluate viral suppression among people living with HIV. By generating reliable population-level data, SILPHIA provides the foundation for strengthening Sierra Leone’s HIV response, guiding resource allocation, and shaping interventions that save lives. Beyond HIV, SILPHIA contributes to the broader public health platform by enhancing surveillance capacity, improving laboratory systems, and building workforce expertise. Statistics Sierra Leone plays a crucial role in SILPHIA by providing technical expertise in survey methodology, data management, and statistical analysis. They are responsible for the preliminary selection of households that participate in the survey, ensuring that the sample is representative and scientifically valid. Not all households are chosen, and this careful selection process enhances the credibility of the findings and their utility for national and international stakeholders.
The NPHA emphasizes that confidentiality is strictly maintained throughout the survey. Participants’ information is protected, and no personal details are disclosed. While stigma around HIV remains a challenge and has made some individuals hesitant to take part, the leadership reassured communities that participation is safe, confidential, and vital for shaping effective health policies. People should not be afraid to participate, as their involvement directly contributes to improving health outcomes for Sierra Leone. As part of the national awareness campaign, the message is clear: HIV IS REAL. Rise, get tested, be safe.
The supervisory visit to Waterloo and Tombo concluded on a forward-looking and inspiring note. The presence of Sierra Leone’s top medical leadership underscored the seriousness of the exercise and the collective resolve to strengthen the nation’s HIV response. By combining scientific oversight, operational excellence, and community engagement, SILPHIA is laying the groundwork for a healthier future. The visit reaffirmed that high-quality, confidential data is the backbone of effective health planning and policy formulation. With the encouragement and guidance they receive, field teams are poised to deliver results that will meaningfully improve health outcomes nationwide. SILPHIA stands as a testament to Sierra Leone’s determination to confront public health challenges with evidence, resilience, and unity of purpose, ensuring that every household selected plays a part in shaping a stronger, healthier nation.
